I just got some material that is just like dynamat extreme. the one with aluminum in the back from ebay. but the problem is i dont think the glue is strong enough to hold that in place in the summer. is there any special way i have to stick it on? i have never done this b4 and neither i know anybody who has done this themselves so i am totally new at this. any help would be greatly appreciated. i want to do my trunk and front doors.
